    TARGET_OPTION_TRANSLATE_TABLE in driver.

breaks plugin support on x86_64-apple-darwin10. The auto-host.h generated for
stage1-gcc contains the expected...


/* Define to enable plugin support. */
#ifndef USED_FOR_TARGET
#define ENABLE_PLUGIN 1
#endif

but the auto-host.h generated for prev-gcc contains...


/* Define to enable plugin support. */
#ifndef USED_FOR_TARGET
/* #undef ENABLE_PLUGIN */
#endif

There is no such problem at r164530 where x86_64-apple-darwin10 properly builds
plugin support.
